Seems to relate to using a slightly different way of synthesizing l-dopa that gives a higher yield.
Any scientists out there who can clarify this? |

if it has anything to do with shortages. And how different will it be, will it be the 'new and improved? if it causes dyskinesia it 's not worth it.

The fungus/mold Aspergilus niger is dark brown or black. The pigment is probably some form of melanin, the production of which uses L-DOPA made from L-Tyrosine by the enzyme tyrosinase. I don't know that I have ever seen a culture of A. oryzae, so don't know if it also makes a melanin-like pigement.
We used to live in a house that had a big pecan tree beside the driveway where I parked the car. At a certain time of summer, the tree had a heavy infestation of aphids which secreted a sugar-rich liquid "honeydew" that fell onto anything beneath the tree. My light tan car would grow nice little black colonies of A. niger in the aphid juice unless I washed it weekly. If I postponed washing it for as long as two weeks, it would become almost completely covered by the black mold, especially on summers when the aphids were especially numerous. Robert |

They still don't know that levodopa therapy is our "gold standard"; how can it be "gaining interest"? The amino acid derivative 3,4-dihydroxy L-phenylalanine (L-dopa) is gaining interest as a drug of choice for Parkinson's disease. Interesting.... Laura |
